| Outline of Final Research Achievements |
To analyze trace elements in single cell and single particle, an ICP analytical system was established by hyphenating droplet direct injection nebulizer, desolvation system and ICP spectrometer. we succeeded to increase mass signal intensity of Mg in single algae cell 30 times by optimizing sample heating region in desolvation system. To evaluate spectral analysis precision of the system, uniform-sized particles of magnetic polymer latex were analyzed and 19.5% of relative standard deviation was obtained from this system. Single human cancer cells were introduced into this system and emission spectra of Mg and Ca, which is contained in single cell pg level, were successfully detected simultaneously.
